Question

In the figure shown, battery `1` has emf`=6V` and internal resistance `= 1Omega.` Battery `2` has emf`=2V` and internal resistance `=3Omega.` The wires have negligible resistance. What is the potential difference across the teminals of battery `2`?

A. `4 V`
B. `1.5 V`
C. `5V`
D. `0.5 V`

Answer 1

Correct Answer - C
Battery `2` is in changing mode
`I=(6-2)/(1+3)=1 Amp`
`V_(2)=E_(2)+Ir_(2)=2+1xx3=5V`
